Biochemical oxygen demand in the Winyah Bay estuary, Georgetown, SC. (Withdrawn).In all estuaries, the biological oxygen demand (BOD BOD: see sewerage. ) is an important part of the ecosystem. BOD can be measured by determining the oxygen consumed through respiration of microscopic organisms in the water. The purpose of our experiment is to determine the BOD occurring in the Winyah Bay estuary near Georgetown, South Carolina Georgetown is the third oldest city in South Carolina and the county seat of Georgetown County. Located on Winyah Bay at the confluence of the Great Pee Dee River, Waccamaw River, and Sampit River, Georgetown is the second largest seaport in South Carolina, handling over 960,000 . At five stations in the bay, water samples are collected and placed in four separate bottles (one for initial and three trials for respiration). Dissolved oxygen content, temperature, turbidity turbidity /tur·bid·i·ty/ (ter-bid´i-te) cloudiness; disturbance of solids (sediment) in a solution, so that it is not clear.tur´bid Turbidity The cloudiness or lack of transparency of a solution. , time (for the tidal cycle), salinity, and UTM (Unified Threat Management) Refers to a stand-alone appliance or a software package that combines a firewall, antivirus, spam and content filtering as well as intrusion detection.

These values, combined with the initial values are used to determine the respiration rates and thus the biological oxygen demand of the system.
